Worried about my smile after getting Volifil injections. Will the effect go away? Is there anything I can do? (Photo)

In May I got my chin injected. The doctor used a product by the name of "Volifil". This was my time using this brand, I typically get Botox or Dysport. After a week, I started noticing that my smile is crooked. My bottom lip won't go down when I smile. It has been a while and in comparison with other areas of the face, the effect has not subsided. Is the effect going to go away? Is there anything I can do to accelerate the process? Thank you!
